Water-cement ratio - Wikipedia

The water-cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or super-plasticizers.. Often, the ratio refers to the ratio of water to cementitious materials, w/cm. Cementitious ...
